[R] Lattice bwplot: Adding mean with panel.points fails in vertical arrangement

Dear collegues, given a structure of data like this: ## Data ### set.seed(100) a - rnorm(60,10,3) s - c(rep(A,20),rep(B,20),rep(C,20)) p - c(rep(d,6),rep(e,6),rep(f,6),rep(g,6),rep(h,6)) df - data.frame(a,s,p) i would like to draw a lattice bwplot in vertical

[R] ggplot2: Controlling line width of panel borders

Dear R-users, i encountered some problems when trying to adjust the line width of the axes and stripes in a plot created with ggplot2. I use the barley dataset of the lattice package to illustrate my problem: library(ggplot2) library(lattice) barley[[SD]] - 5 limits - aes(ymax=barley$yield +

Dear R-users, i want to plot gene regulation data in a lattice barchart. To illustrate the problem i encounter, the following code uses the barleydataset: library(lattice) barley[[SD]] - 5 PLOT - barchart(data=barley, yield~variety|site, groups=year,origin=0, as.table=TRUE,

[R] Concatenating two vectors into one

Dear users, a very simple question: Given two vectors x and y x-as.character(c(A,B,C,D,E,F)) y-as.factor(c(1,2,3,4,5,6)) i want to combine them into a single vector z as A1, B2, C3 and so on. z-x*y is not working, i tried several others function, but did not get to the solution. Thanks

[R] xYplot customizing y-axis scaling

Dear list, using the packages Hmisc and lattice i produced some nice xYplots. However, since the data range of the conditioning variable is very big, i need to define more than one y-scale for the plot (in some panels you just see a flat line of data points very close to the x-axis), e.g.
